Which insect has Simple metamorphosis and belongs to Blattodea?

• A. Giant Water Bug
• B. German Cockroach
• C. Green Bottle Fly
• D. Flea Beetle

Answer: (B)

Incomplete metamorphosis means the insect goes through egg, nymph, and adult, with nymphs that resemble smaller versions of the adult and no pupal stage. Blattodea, the group that includes cockroaches, shows this pattern. The German cockroach is a member of Blattodea, so it fits both criteria: it belongs to this order and undergoes simple (incomplete) metamorphosis. The other options come from different orders and/or have a different development. A Giant Water Bug is a true bug (Hemiptera) with incomplete metamorphosis but not in Blattodea. A Green Bottle Fly is a fly (Diptera) with complete metamorphosis. A Flea Beetle is a beetle (Coleoptera) with complete metamorphosis.
